----------------------------------------
@Bruno
I'm +1 on the bigtop-utils approach too, but that'll be some work. How about if
we, at least, put the following into
all of our /etc/default/* files for now:
RPM:
# Update this value to point to the installation of Java on your system
JAVA_HOME=/usr/java/latest
Debian:
# Update this value to point to the installation of Java on your system
JAVA_HOME=/usr/lib/jvm/java-6-sun
> Standardize JAVA_HOME detection

> The Hadoop packages go through some effort (see
> /usr/lib/hadoop-0.20/bin/hadoop-config.sh) to guess at a good JVM to use if
> JAVA_HOME isn't set. For example, if both OpenJDK and Oracle JDK are
> installed, hadoop-config.sh will choose Oracle every time. Other packages
> that Bigtop integrates, don't follow the same practice (ZK, Pig, etc.). It
> would be nice to have this common code shared.
